Secured Raw Material Supply

Omya always favors a strategy of acquisition using its own resources rather than having suppliers of raw material.

Omya always has a long-term vision in terms of deposits – a plant cannot be constructed without usable reserves being ensured for at least 30 to 40 years (or more, if possible).

Omya's deposits are well known geologically (mappings, drillings). This allows us to obtain a long-term 3D vision of the deposits and to establish precise mining development, thus saving on mining costs as follows:

In open pits:

The waste dumps are located outside the deposit area

The plant is built outside the quarry area

In underground mines:

Excavation of galleries is made according to a precise plan avoiding unusable areas

The vein is not followed, as was often the case in old mines

As a result of this well-prepared reconnaissance of deposits, it is easier to take into account possible risks (stability, falling rocks) and to ensure better site restoration after (or sometimes during) mining.
